Hi Lu,
We are sorry you are having issues with the LM92. We have a formal process for handling customer returns. I'm sorry but I cannot help you directly. Please contact the distributor you purchased your LM92s from for returning the parts.
I would also like to say that we working diligently on new temp sensors. I'm not at liberty at the moment to disclose exactly what we are working on - all I can say is stay tuned. (Hopefully you will!)
You are replying to a post that was started some time ago, so I am assuming that you are also having issues with lock up. If you would like further help to debug the issue on E2E, please describe your problem in more detail. Scope photos of the communication before the lock up and a schematic would help us understand your problem further. Not all problems have the same root cause, I always learn something new…
Take care,
